Binding Semantics for Varying Input/Output Data

-----------------------------------------------

Table 23 summarizes the valid binding semantics for varying input parameters
115
One can also use TANGENT and BINORMAL instead of TEXCOORD6 and
116
TEXCOORD7. These binding semantics map to NV_vertex_program2 input
117
attribute parameters. The two sets act as aliases to each other.
